CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 325,200, dated August25, 1885.-

Applicntion filed June 6, 1885.

To all whom it may concern:

Be it known that I, JosnUA HORATIO DY- MOND, a citizen of the UnitedStates, residing at Garbondale, in the county of Osage and State ofKansas, have invented certain new and useful Improvements inOar-Couplings, of which the following is a description.

This invention relates to that class of carcouplings in which the linksand draw heads are designed to couple automatically; and its object isto provide a link the two ends oi which shall be alike, and draw-headsalike at both ends of each car, whereby either end of any link willengage either end of any car,

I5 and cars may be coupled with each other at either end.

To this end my invention consists in the construction and combination ofparts formin g a carcouplin g, hereinafter described and Figure l is aside elevation of my invention.

Fig. 2 is an end view of the draw-head. Fig. 3 is a transverse verticalsection of the link,

and Fig. 4 is a plan view of the link.

A represents my draw-head, which may be of any usual construction in allrespects, ex cept at its coupling end. To this I give a pcculiarly-shaped mouth, B, which is wider than 0 its height,communicating with an enlarged throat, (I, the enlargement producingrectangnlar shoulders I) behind the lips E. The lower lip slants outwardand to the left, forming a spiral or screw shaped openin 33 bodyprovided with two pairs of lateral wings G, which terminate at the rearin rectangir lar shoulders H, and which incline spirally forward toengage the spiral slantofthe lips E.

by a rigid arm to hold it in or return it to its normal position withits wings vertical. The bodyand wings of the link may, when horizontal,enter the mouth of the draw-head. Then 5 it turned into averticalposition the shoulders H of the wings will engage the shoulders D of thelips in the draw-head, whereby the car 0 is tapered and smoothly roundedto readily l link is free to be withdrawn.

1 is the link, having a cylindrical stem or I J is a weight hung to oneside of the link I to secure by Letters Patent, is-

enter the draw-head. At the rear of the enlargement G the throatcontinues into the draw-head as a round hole, K, trumpet-shaped at theenlargement to receive the projecting end of the link, whereby the linkmay beheld level by one end, and the link-wings resting against theshoulder around the hole K hold the link to push it into anotherdrawhead.

In service one end of the link is placed in one draw-head,and when thisdraw'head meets another the stem of the free end of the link will enterit, and the wings G, turning upon the spiral lips E, will also enter andpress the shoulders D, when the weight J, which has been swung up to oneside by the turning of the link, will, now that the wings are free, turnthem to a vertical position behind the shoulders 'D, thus coupling thecar. To uncouple it the weight may be swung either way to nearly ahorizontal position, when the The spiral of the drawhead lips and ot'the links may be made either right or left handed, but it is better thatthey should all be made from one pattern, so that the train-hands neednot look to know how they are. The throats are open at the sides to givebetter opportunity to aid or loosen a sticking link.

11 represents a bar-pivoted at one end by a bolt, M, to the drawhead andadapted to rest on a stud, N, on the other draw-head, or to swing downwhen set free to do so. When itis desired to push acar back to any point3 and leave it on to hit it akick, in "ailroad parlance, the ball J isto be raised and its arm left resting on the bar L. By this means thelink is set so that it may draw free from the head. As soon as thedraw-heads separate, the bar will swing down out of the way.

\Vhat I claim as my invention, and desire o 1. The combination of adraw-head having a transverse]y-elongated mouth, lips spirally slantedforward and shouldered at their rear, an enlarged throat open at itssides behind 9 5 the lips, and having a round rearward extension, and alink having a cylindrical body and lateral wings, spiral at their outerends and shouldered at their inner ends and weighted at one side, thebody of the link ICO projecting at each end beyond Ihesnid wingsstantiull as shown and described, whereby substantially as shown anddescribed. the said weighted arm may be temporarily 2. The combinationof a link adapted to t supported and finally set free, as set forth.turn on its longitudinal axis, and provided t j; with a Weighted arm, abar pivoted at one end to one draw-head, and a stud projecting from theside of the other draw-head, sub- JOSHUA HORATIU DYMOND. \Vitncsses:
